Lysozyme exists as an antibacterial mechanism across multiple kingdoms of life. The first human experience with antibacterial lysozyme was in 1909, when Laschtschenko discovered the lysozyme within egg white and its capability of forming a barrier between the outside world and the embryo inside. But the enzyme was not properly given a name until 1922, when the nobel laureate, Alexander Fleming identified its basic function of “ rapidly lysing (ie.., dissolving) certain bacteria”. In 1965, structural biologist David Chilton Phillips was able to conduct an X-ray crystallography on lysozyme and explain the protein’s role of chemical catalysis with its physical structure. Phillips’ theory of chemical lysis with lysozyme was later revised by biochemist Daniel Koshland.
